My friend saw the DVD logo next to the Nav slot and insist that I can play movies. Not only do I think he's incorrect but don't want to even try.

Also, I have the iPod integration with AUX cable and USB slot and was wondering if I have a built in hard drive like the new cars have and what else can be done with these two slots? Does one charge and the other for integration with NAV? I have a 2008 135i.
